Going to convert the 68 to an electric fuel pump. Looking for pump / regulator recommendations and experiences with installation and opearation
When wiring an electric fuel pump spend the extra time and money to be safe. Use a set up so that the pump would only run when starting (feed from the activation side of the solenoid) and when engine running. For the latter use an oil pressure switch. No oil pressure, no fuel pump running. Would not want fuel running all over the place in case of an accident would you?
I intend to use a tachometric relay from a fuel injection set up
I’ve run electric fuel pumps exclusively since 1994 since my motor never had provisions for a mechanical pump.
I started out with Carter pumps all mounted right in front of the tank because electric pumps are designed to better PUSH fuel instead of PULL. They would last an average of about 3-4 seasons before giving up. I went through about three of those. Since the Edelbrock Carbs only like something in the neighborhood of 5 to 5.5 pounds of pressure, I always ran them with a regulator mounted in various places from back near the tank to inside the drivers side wheelwell, to right up next to the carb.
I’ve since switched to a Holley Red pumps and they have lasted much longer. I did have one fail but it was after about 10 years of faithful service. I’m currently running one now and always have a spare one “in stock.” With the Red pumps, I’ve run it both WITH and WITHOUT a regulator (currently without) and it seems the car doesn’t run any different. 
Both pumps were about the same in the “noise” department. But neither one can be heard above the Flowmasters. 
For the record, I’ve always powered the pumps via a Bosch syle relay for a steady supply of current.
yeah, the red pump is where it be at for a reliable street car. Blue pump is overkill for a street car.
I would agree on the red pump and a Holley fuel pressure regulator with gauge. Now you are going to also need a fuel filter in line that will accommodate the higher working pressure of the pump so try looking at the Aeromotive stuff here http://aeromotiveinc.com/products-page/ you might even find a pump you like as their stuff is top notch. For fuel pump cut out in case of an accident I would get a Ford enertia switch and mount it in the trunk somewhere like they did for the Mustangs and other Ford cars from the lat 80’s and up. I have used the ones from a early 90’s Mustang on my 2 fuel injection swaps. In this article they show you a guy installing one on his 60’s Mustang. http://www.mustangandfords.com/techarticles/engine/9414_50_ford_performance_tips_tricks/photo_28.html
I have been pretty happy with my Mallory 110 pump. Ran it for about 3 years as a daily driver, and now just occasionally. All over a span of about 14 years, with about 10 just sitting. I did rebuild it after it sat so long.
